Here is a simple example which shows the problem. Of course you have to run it on 
a machine without a floating point unit by setting emu387:

set emu387=c:/emu387.dxe 

// FPTEST.C
#include <stdlib.h>
#include <stdio.h>

int main(void)
{
        double dfVal;
        
        char *psz = "1.23";

        dfVal = atof(psz);
        printf("String %s Floating value %f\n",psz,dfVal);
        return 0;
}

Here are the results I got:

C:\>set emu387=c:/emu387.dxe        
                                    
C:\>fptest                          
String 1.23 Floating value 0.000000 
                                    
C:\>set emu387=c:/wmemu387.dxe      
                                    
C:\>fptest
